屋顶绿化降温增湿作用对环境温度的影响研究

The Influence of Roof Greening's Cooling and Humidification on Environment Temperature

通过对不同密度屋顶绿化种植面积的降温作用以及对比花园内部绿化场地和非绿化场地之间主要微环境因子(主要为温度和湿度)的垂直梯度变化,研究了屋顶绿化降温增湿作用对大气温度的影响。结果表明:种植密度越大,降温的效果越明显;同时,屋顶绿化后,不同垂直高度的温度和湿度变化较之于未绿化的屋顶差异不甚明显。

Through themeasurement of the cooling effect of the roof greening with different planting densitiesand the comparison of vertical gradient varianceof the mainmicroenvironmental factor （temperature andhumidity）of between the inner greening field and non--greening field of the garden, the article studies the influence of roof greenings effect of cooling and humidification on environment temperature. The results show that the larger the density, the better the effect. At the same time,the article finds out that after the roof greening, the temperature and humidity ofdiffer- ent vertical height have no obvious difference compared to that of the non--greening roof.
